Individualization of exertion while monitoring functional state during exercising

Abstract

Background. Individualization in workloads is important as to get optimal benefits of exercising and longterm adaptation. Monitoring of heart rate (HR) during exercising could be valuable for the fed-back formation. The HR at state of absolute rest, i.e. after of 8 hours of sleep, differs from values calculated at state of relative rest. This study was designed to determine individualization of workloads while the task of training session is to develop functional abilities of cardiovascular system. Methods. The participants of the study were 76 healthy adults who had to perform the same pulse rate, i.e. HR self-examination at absolute and relative rest states. In order to evaluate the difference of HR between the real and relative rest, participants had to calculate their pulse for 30 seconds at each 5 days. The results obtained during the study were analysed according to age and gender by performing calculations of HR Reserve, and the recommended intensities of exercising at 50% of HR Reserve; 70% of HR Reserve; 85% of HR Reserve, and calculation of sum of HR for 40 minutes training session was performed. Results. Significant difference was found while comparing the averaged values of HR obtained at real and relative rest; greater difference between relative and real resting conditions was observed in younger age groups. While calculating the recommended HR values for choosing the intensity of exertion, evaluating the real and relative rest, it can be noted that the recommended HR meanings during exercising significantly differed. In order to get the effect of training when HR should be 50% of HR Reserve, or when HR should correspond 70% of HR Reserve. Conclusion. The algorithm for feed-back formation could take into account the initial values of HR corresponding to the state of absolute rest, i.e. after of 8 hours of sleep. The HR at relative rest state is different than in real rest state why the algorithm for feed-back formation should take into account
